1000m. Start up the Couturier, then climb the first rectilinear gully to the left of the Bourges-Mizrahi, 4 pitches of 70/80 degree ice (sometimes thin). From the top of the gullies, go up the snow slope on the right to exit at the saddle on the E ridge of the Grande Rocheuse. - Taken from "Snow, Ice and Mixed".
Route is not as sustained as this description may indicate. Short sections at 80 degrees, but for the most part is about scottish III. Protection was not readily available on my ascent in the lower gullies. Early start essential so as to have reached the difficulties by sunrise. A recommended route!Autheman, Dellavolpe, Vimal 05/Feb/1992
